What Are Bifocal Lenses and How Do They Work?

Bifocal lenses are prescription lenses designed to provide two different optical powers in one pair of glasses. The upper portion is generally used for distance vision, while a lower segment provides additional power for close work such as reading. This design can be useful for people who need correction at more than one viewing distance.

Bifocals are commonly associated with presbyopia, the age-related change that makes near focusing more difficult. Rather than carrying separate distance and reading glasses, a wearer can use one pair for both tasks. The exact prescription should come from a current eye examination.

How the Two Zones Work

Traditional bifocals have distinct viewing areas. When looking through the upper section, you use the distance prescription. When you look through the lower segment, the added near power helps with close objects. Because the powers are separated, many traditional bifocals have a visible segment line.

There may be a short adjustment period. Your eyes and head need to become familiar with changing between the two zones, particularly when moving from reading to looking across a room.

Are Bifocals Right for You?

Bifocals are not automatically the best choice for everyone. Some people prefer progressive lenses because they provide a gradual transition and an intermediate viewing area. Others prefer the defined zones of bifocals because the design is straightforward.
